-We have a custom designed 3D printed Thread Indicator Dial (TID). It is works exactly the same as the original manufacturers dial so the {{ :equipment:metalshop:metallathe:harrison_m250_machine_manual_enhanced.pdf |PDF of Harrison M250 Manual}} can be used as a reference. There are in fact two TIDs a Green one with a 20 tooth drive cog and a Blue one [COMING SOON] with a 21 tooth drive cog. Which one you use depends on the pitch of the thread you are wanting to cut, see table below.
